How to Use the Penis Size Calculator
This tool estimates erect length based on common anthropometric correlations. All inputs must be in metric units.
- Enter your Height in centimeters (e.g., 175).
- Enter your Weight in kilograms (e.g., 70).
- Enter your Shoe Size in EU sizing (e.g., 42).
- Enter your Age in years (must be 18 or older).
- Click "Calculate" to see your estimated erect length in centimeters.
Note: The result is clamped between 5 cm and 25 cm. The formula uses a multiple regression model: 0.35×height + 0.15×weight + 0.5×shoe size − 0.1×age − 20.

Frequently Asked Questions
This calculator provides a rough statistical estimate based on population averages and anthropometric correlations. It is not a precise measurement and should not be used for medical decisions. Individual variation is significant.
The calculator uses a statistical model that cannot account for individual biological variation. Factors like genetics, hormone levels, and development during puberty play major roles that are not captured by height, weight, or age alone.
No, this calculator is intended for adults only. Penile growth typically continues until the late teens or early twenties, so estimates for minors would be unreliable and inappropriate.
According to a comprehensive 2015 review of over 15,000 men, the average erect penis length is about 13.12 cm (5.16 inches). However, averages vary by population and measurement method.
No, scientific studies have found no reliable correlation between shoe size and penis size. This calculator does not use shoe size for that reason.
